This is an odd weekend at the box-office, with no wide openings on Friday following the Fourth of July on Wednesday. Steve Mason at Fantasy Moguls is predicting “Transformers,” which opened Monday night, will lead the traditional three-day weekend with around $67 million, bringing the flick’s cume to $152 million — the best-ever six day total for a non-sequel. After a slower start than other recent Pixar animations, “Ratatouille” seems to be holding well thanks to great reviews and word of mouth, with Mase prognosticating $33 million over the weekend, for a total of $123 million by Sunday night. “Live Free or Die Hard” will collect another $17 million, Mase thinks, for $83 million or so to date. The No. 4 flick, the critically savaged Robin Williams comedy “License to Wed,” isn’t expected to break into the double digits over the weekend, with a cume of around $17 million since its Tuesday opening. Expect an early debut on DVD.
